Darren.... start by reading the below sites:

I have to read between the lines here.... one owner, replaced carbs with (?) hopefully another set of 77-78 carbs. 34k miles and you haven't checked the points?
WOW! I think the timing is off, too!

Check the above websites... get a fresh set of points and condensers from Honda or m/c shop or Ebay and then follow the procedures in the above sites, along with some point grease from an autoparts store or a H-D dealer.

I suspect that your points are barely opening at all, resulting in very retarded ignition timing. When you change out the points, remove the point plate and check the spark advancer function for good advance/retard on the springs/weights. Clean and lubricate as necessary. Mark the point cam before you remove it from the advancer, as you may be able to put it on backwards and confuse yourself a bit.
